5. WDM Single Fibre Models
The GCR2000 Series have models available that support Wave Length Division Multiplexing.
This allows the media converter to use a single fibre optic strand to transmit and receive
data over the single fibre. This is achieved by transmitting and receiving data on different
wavelengths.
Single Fibre Model
1310nm Single-Mode 20Km
1550nm Single-Mode 20Km
Note:
The 1310nm and 1550nm models must be installed in pairs. i.e. install 1310nm model at one
end of the fibre run and 1550nm model at the other end.
